[TowerTalk] AB-577 Portable Mast

Hi all,
I am looking for information on a east coast source for a portable 50'
surplus military mast, AB-577. The mast is 8 - 6' sections of 5 inch
diameter aluminum tubing that is loaded into a launcher and winched up
vertically.
It was readily available on the west coast several years ago, but shipping
is almost prohibitive. The mast was used to support the 20 meter fixed
array on the cover of CQ last fall.
